At NorthWestern Energy, we are dedicated to helping you save energy and money through Efficiency Plus (E+). One of the easiest ways to get started is with a FREE home energy audit.

Our trained specialists come to your home and analyze your home’s energy usage. You’ll receive tips to manage your energy usage more effectively, a customized report with recommendations of cost-effective energy improvements which may help you make appropriate investments.

The information you provide is sent directly to the NorthWestern Energy E+ Audit Team and will only be used to schedule a home energy audit. You can be assured all contact information is private.

Thank you for your interest in the E+ Audit for the home program. We will contact you soon!

This program is limited to NorthWestern Energy residential natural gas or electric space- or water-heating customers in Montana or South Dakota. It does not appear that this home qualifies. If you have questions, please call 800-823-5995.
